+# To support the Sun linker we need to make it behave like the GNU linker
+# for orphaned sections. That means generating __start/__stop symbols
+# for them and that means some nopoly-atheist-withoutfood level trickery.
+# We enumerate all the section names we wish to generate symbols for.
+# The good news is that it's unlikely for NetBSD to grow any more
+# link sets, and even if it does, it'll be a build-time failure
+# on Sun platforms so it's easy to catch and mend the list below.
